The invention relates to a method of conveying flat, flexible products, in particular printed products, in which the products are conveyed continuously by means of a conveying device in an overlapping formation to a transfer region and are picked up there by an outward conveyor. The outward conveyor comprises grippers which are moved along a movement path, can be controlled individually to open and close and have at least two gripper jaws, whose alignment relative to the movement path can be varied. According to the invention, the grippers are moved in such a way that the gripper jaw facing the conveying device engages in the manner of a shovel underneath the trailing edge of at least one product resting partly on the trailing product in the transfer region, without said product having previously been raised off the trailing product, and then raises said product. The products, before or after being engaged underneath, are braked relative to trailing products and/or fixed in their position. The invention also relates to an apparatus for implementing the method.

The invention claimed is: 1. A method of conveying flat, flexible products, such as printed products, comprising the steps of: conveying the products continuously, in a generally horizontal plane into a transfer region, in a formation in which the products overlap one another at least partially as viewed in the conveying direction, with the trailing edges of the leading products overlapping leading edges of the respective trailing products in the case where there is a partial overlap; providing a gripper conveyor including a plurality of grippers movable along a movement path which passes through said transfer region, each of said grippers including a first gripper jaw and a second gripper jaw; moving the gripper conveyor whereby the grippers are moved in such a way that one of the gripper jaws engages in the manner of a shovel underneath the trailing edge of at least one product while said trailing edge is resting on the trailing product in the transfer region and then raises said one product off of said trailing product; and before or while said trailing edge of the at least one product is being engaged underneath, braking or otherwise stopping the product being raised relative to trailing products. 2. The method as claimed in claim 1, wherein the grippers are moved in the transfer region in such a way that the one gripper jaw is moved relative to the at least one product to be picked up along a path which is substantially shaped like a circular arc. 3. The method as claimed in claims 1 or 2, wherein the gripper is moved relative to the at least one product to be picked up in such a way that the gripper jaw which engages underneath is pivoted from a first alignment into a second alignment substantially in the plane of the product. 4. The method as claimed in claims 1 or 2, wherein the products are conveyed to a braking device and are braked as a result. 5. The method as claimed in claim 4, wherein the speed of the grippers is chosen to be matched to the conveying speed of the conveying device in such a way that a predetermined number of products are pushed onto a stop to form a stack, which is gripped as a whole by the gripper. 6. The method as claimed in claims 1 or 2, wherein the movement path in a first portion arranged upstream of the transfer region, and in a second portion arranged downstream of the transfer region, runs substantially at right angles to the convoying direction. 7. The method as claimed in claim 3, wherein the movement path in a first portion arranged upstream of the transfer region, and in a second portion arranged downstream of the transfer region, runs substantially at right angles to the conveying direction. 8. The method as claimed in claim 4, wherein the movement path in a first portion arranged upstream of the transfer region, and in a second portion arranged downstream of the transfer region, runs substantially at right angles to the conveying direction. 9. The method as claimed in claim 5, wherein the movement path in a first portion arranged upstream of the transfer region, and in a second portion arranged downstream of the transfer region, runs substantially at right angles to the conveying direction.
